      The ->inflight counter may be negative (-1) if
      
      1) blk-iolatency was disabled when the IO was issued,
      
      2) blk-iolatency was enabled before this IO reached its endio,
      
      3) the ->inflight counter is decreased from 0 to -1 in endio()
      
      In fact the hang can be easily reproduced by the below script,
      
      H=/sys/fs/cgroup/unified/
      P=/sys/fs/cgroup/unified/test
      
      echo "+io" > $H/cgroup.subtree_control
      mkdir -p $P
      
      echo $$ > $P/cgroup.procs
      
      xfs_io -f -d -c "pwrite 0 4k" /dev/sdg
      
      echo "`cat /sys/block/sdg/dev` target=1000000" > $P/io.latency
      
      xfs_io -f -d -c "pwrite 0 4k" /dev/sdg
      
      This fixes the problem by freezing the queue so that while
      enabling/disabling iolatency, there is no inflight rq running.
      
      Note that quiesce_queue is not needed as this only updating iolatency
      configuration about which dispatching request_queue doesn't care.

      ide: ensure atapi sense request aren't preempted · 9a6d5488
      Jens Axboe 提交于
      There's an issue with how sense requests are handled in IDE. If ide-cd
      encounters an error, it queues a sense request. With how IDE request
      handling is done, this is the next request we need to handle. But it's
      impossible to guarantee this, as another request could come in between
      the sense being queued, and ->queue_rq() being run and handling it. If
      that request ALSO fails, then we attempt to doubly queue the single
      sense request we have.
      
      Since we only support one active request at the time, defer request
      processing when a sense request is queued.

      md/raid5: fix 'out of memory' during raid cache recovery · 483cbbed
      Alexei Naberezhnov 提交于
      This fixes the case when md array assembly fails because of raid cache recovery
      unable to allocate a stripe, despite attempts to replay stripes and increase
      cache size. This happens because stripes released by r5c_recovery_replay_stripes
      and raid5_set_cache_size don't become available for allocation immediately.
      Released stripes first are placed on conf->released_stripes list and require
      md thread to merge them on conf->inactive_list before they can be allocated.
      
      Patch allows final allocation attempt during cache recovery to wait for
      new stripes to become availabe for allocation.

      Revert "mm, memory_hotplug: initialize struct pages for the full memory section" · 4aa9fc2a
      Michal Hocko 提交于
      This reverts commit 2830bf6f.
      
      The underlying assumption that one sparse section belongs into a single
      numa node doesn't hold really. Robert Shteynfeld has reported a boot
      failure. The boot log was not captured but his memory layout is as
      follows:
      
        Early memory node ranges
          node   1: [mem 0x0000000000001000-0x0000000000090fff]
          node   1: [mem 0x0000000000100000-0x00000000dbdf8fff]
          node   1: [mem 0x0000000100000000-0x0000001423ffffff]
          node   0: [mem 0x0000001424000000-0x0000002023ffffff]
      
      This means that node0 starts in the middle of a memory section which is
      also in node1.  memmap_init_zone tries to initialize padding of a
      section even when it is outside of the given pfn range because there are
      code paths (e.g.  memory hotplug) which assume that the full worth of
      memory section is always initialized.
      
      In this particular case, though, such a range is already intialized and
      most likely already managed by the page allocator.  Scribbling over
      those pages corrupts the internal state and likely blows up when any of
      those pages gets used.
